In general terms, the replication cycle of lentiviruses, including HIV-1, closely resembles that of other retroviruses.1 There are, however, a number of unique aspects of HIV replication; for example, the HIVs and SIVs target receptors … WebSingle-stranded RNA viruses such as HIV carry a special enzyme called reverse transcriptase within the capsid that synthesizes a complementary ssDNA (cDNA) copy using the +ssRNA genome as a template. The ssDNA is then made into dsDNA, which can integrate into the host chromosome and become a permanent part of the host.
